Uranium mining and milling produces very large amounts of waste, primarily in the form of excavated rock, ores that contain too little uranium to be profitable and mill tailings. Mill tailings are produced during the processing of uranium ore. They are sand-like, crushed rock residues, which are left over after the uranium has been extracted.
